Microsoft today released updates to Windows 10 patching a critical vulnerability found in its Server Message Block (SMB) version 3 protocol. Released to Windows 10 versions 1903 and 1909, the Cumulative Update KB4551762 includes a patched SMB 3.1.1 protocol component. The update mitigates a security vulnerability with SMBv3 chronicled under CVE-2020-0796, which enabled remote code execution. "To exploit the vulnerability against a server, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv3 server. To exploit the vulnerability against a client, an unauthenticated attacker would need to configure a malicious SMBv3 server and convince a user to connect to it," reads the Microsoft security advisory. To get the update, simply make Windows Update "check for updates," or get the msu files from the link below.
